The Teen Moms are an endless source of scandal -- and most of it revolves around their many relationship messes. Take Jenelle Evans for instance. Who could forget her drug-fueled romance with Kieffer Delp. It was like watching a head-on train collision in slow motion. During season 4 of Teen Mom 2, they started using heroin together. She eventually left him because of it, which was probably the most adult move she had ever made -- until now. While Jenelle and Kieffer are not back together, what she recently did for him reveals how mature this once-disastrous reality star is becoming.

She is reportedly now clean and sober thanks to Narcotics Anonymous, but her ex may not have fared so well. His recent tweets are certainly worrisome. When a Twitter follower called him a "crackhead," he shot back, "Smack head [heroin] get it rite if your God to judge me."

More disturbingly, he also wrote:

I'm hurting so f— bad I can taste it in my throat.... please.... someone... Please...

Everyone immediately suspected he was going through some sort of withdrawal -- or at least hoped that was the case. While it's not clear what is going on with the poor guy, he is clearly struggling, and it was nice to see that Jenelle reached out to offer him some much needed support. She wrote:

I promise u, u can make it through this.

Honestly, I think Jenelle’s reaction to his tweets was one of the most mature, grown-up thingsshe has ever done. It can be hard to help out an ex, especially if the relationship was particularly rocky or troubled. Kieffer had once admitted that he peer pressured Jenelle into using the drug. She offers real sincere words of encouragement. Kieffer was certainly grateful, writing, "I sure as f-- will ... I won't give up." Let's hope so.
